Started a Niche Job Board... Now What?

As the title suggests. I created a niche job board in my industry. I felt that there was a massive gap as far as searching for opportunities and gathering resources within my field, hence me making the job board. Now that I've gotten here though... I'm not sure what to do next. I've steadily been growing a social following (very small) on LinkedIn, and have been having a go at making TikToks centered around my startup. I've been steadily growing site viewership (couple hundred a day), but it's not translating into subscriptions. I currently have a paywall on my job board ($5/wk, $15/mo and $30/yr). I've gotten a whopping 1 subscriber, which is amazing, I don't want to sound ungrateful since this is the first project I've ever built that I was able to get anyone to deem it good enough to open their wallet, but since that initial subscriber... nothing. My question then is, should I remove the paywall all together for now to make it more accessible and get more eyeballs on it? I would refund my one subscriber if I make it free. My monetization would then strictly be on companies purchasing job posts, but truthfully my job board is nowhere close to bringing in enough traffic to warrant a company's recruiting/HR team to buy a spot.

Also, as far as "marketing" I set up automations that create an organization post on the company's LinkedIn page so every hour it posts a new job with a link to apply for the job on my board (no subscription required). Then, like I said before, creating TikToks centered around the job board and questions about the industry.

This is my first real go around, so anything would be helpful. Thoughts?
